The field descr would presumably hold the values I originally had in the field Taxon - e.g. the names of various taxons, like 'Mammalia' and 'Canis-lupus.' The field id is just a numerical key, and I already have the numerical values for parentid.
But what am I supposed to put in the field taxonid?
I'm going to shut up - because the OP might be better served by a single voice and other on this thread are surely more capable.
